Information

Overview Manuals Common Applications Product Precautions
Bently Nevada 330173-00-03-10-02-CN suits a constrained mounting position where a small probe body is needed, such as a location between thrust-bearing pads.
  • Uses a compact 30 mm case with no unthreaded section.
  • Joins to the extension cable through a locking miniature coaxial connector.
  • Uses TipLoc molding to bond the sensing tip to the probe body.
  • Produces both static-position and dynamic-vibration information through its matched conditioner.

The smaller tip does not reduce the side-view or tip-spacing requirements of the 8 mm system. Leave the electrical clearance dictated by the transducer arrangement rather than choosing a closer spacing solely from the probe body diameter.

Important Notice: Keep the selected sensor and extension cable associated with their electrical system length; do not transfer the performance limits of an all-XL 8 mm system to this 5 mm probe channel.

Bently Nevada 330173-00-03-10-02-CN Official Technical Reference Excerpt (PDF)Bently Nevada 330173-00-03-10-02-CN Installation & Commissioning Guide (PDF)

The technical excerpt covers transducer construction and performance. The installation guide develops mounting, connection and signal-verification procedures for the selected assembly.

Constrained thrust measurement
Place a small sensing body at a conductive thrust target.
Fluid-film bearing monitoring
Acquire displacement where the mounting arrangement favors a 5 mm probe.
Speed-reference sensing
Observe target passages through an appropriately configured measurement channel.
Static clearance tracking
Follow the average probe-to-target distance separately from its vibration component.
Protect the measuring target, cable path and electrical connections when installing Bently Nevada 330173-00-03-10-02-CN.
1
Verify the M8 x 1 mounting thread before inserting the case.
2
Check that the 30 mm case reaches the target without stressing the lead.
3
Retain the required metal clearance around the sensing tip.
4
Identify the complete five- or nine-metre electrical arrangement.
5
Protect the cable junction for its actual oil and moisture exposure.
6
Avoid using a different target alloy as an unqualified calibration substitute.
7
Sweep displacement with the matched conditioner and monitor connected.
8
Confirm that the restored channel represents the intended shaft position.

Technical notes

A 1.0 m probe has a nominal DC resistance of 7.59 ± 0.50 Ω. Use the disconnected probe for this check and treat continuity as a preliminary check before displacement calibration.

FAQ View All FAQ

  • Does the 30 mm case of 330173-00-03-10-02-CN permit 30 mm of threaded engagement?
    No. Maximum M8 x 1 thread engagement is 12 mm with the matching internal thread fit. Excess engagement can cause binding even though the nominal thread size is correct.
  • Which field cable is recommended between the conditioner used with 330173-00-03-10-02-CN and the monitor?
    Use a shielded three-conductor triad in the 16–24 AWG range. This field cable carries the conditioned signal and is distinct from the calibrated probe extension cable.
  • How does probe temperature affect the displacement accuracy of 330173-00-03-10-02-CN?
    Across -35 to +177 °C, the typical incremental scale factor remains within ±10% of 7.87 V/mm and straight-line deviation within ±0.076 mm. These limits differ from the room-temperature figures.
  • Does the smaller sensing body of 330173-00-03-10-02-CN allow closer surrounding metal?
    No. The 5 mm package helps with physical mounting space but does not reduce the side-view clearances or tip-separation requirements of the 8 mm system.
  • How is incremental scale factor evaluated for a system using 330173-00-03-10-02-CN?
    It is measured in 0.25 mm displacement increments across the linear range. The nominal value is 7.87 V/mm with a typical ±6.5% tolerance including interchangeability error under the reference conditions.
  • What bandwidth can the conditioned signal from 330173-00-03-10-02-CN support over the specified field wiring?
    The system frequency response is 0–10 kHz at +0/-3 dB with up to 305 m of field wiring. Longer wiring or remote barriers require assessment of high-frequency signal roll-off.
  • How far apart should two 330173-00-03-10-02-CN sensing tips be to limit cross-talk?
    Typical minimum separation is 40 mm for axial position or 38 mm for radial vibration. Target diameter and operating gap also matter; the cross-talk guidance assumes the specified shaft and gap conditions.
  • Why does the pressure seal of 330173-00-03-10-02-CN need extra attention near its low-temperature limit?
    Although the probe range starts at -35 °C, exposure below -34 °C may cause premature pressure-seal failure. The probe is not pressure-tested before shipment, so the application must provide appropriate fluid and gas containment.
